2 Claims. (01. 131-495) My invention relates to pipes for smoking tobacco andmore particularly to means to render the smoking of the tobacco more enjoyable throughout the life of the use thereof.

One of the objections to be found with the ordinary smoking-pipe is that its extensive use will burn or dry the tongue, and numerous ways have been proposed heretofore to cool the smoke drawn from the tobacco. These have been either too complex in structure, inconvenient to clean, or improperly designed to accom plish the results wished for, and generally they are unsatisfactory from the practical and commercial standpoints.

Another of the objections found with smokingpipes as heretofore marketed is that the flavor of the tobacco is contaminated by the wood of the pipe and the substances used in the treatment thereof during manufacture so that the pleasure of smoking is spoiled, especially in the first months of use of the pipe. This period is known as the breaking-in period.

In my opinion, since making my invention, the true and delicate flavor of the tobacco is contaminated also by the carbon and other substances formed in the pipe during the breakingin period and which remain in the pipe even after it is cleaned.

' It is one object of'my invention to provide a pipe for smoking tobacco wherein the aroma of the tobacco is not contaminated by the pipe, even when made of the less expensive and less suitable woods or other materials. e

It is another object of this invention to provide I a' tobacco pipe that requires no breaking-in period and will afford the same quality of smoke throughout its life.

It is another object of my invention to provide a construction of tobacco pipe wherein the heat in the bowl containing the tobacco is quickly dissipated and the smoke also is cooled in an unheated portion of the pipe.

It is a further object of this invention to provide a tobacco pipe wherein the tobacco particles are completely consumed and reduced to ash so that there is no waste in the use thereof.

It is a further object of this invention to provide a very simple modification of the structure of the ordinary tobacco smoking pipe whereby the pleasure of use thereof is greatly increased and the pipe is readily cleaned.

It is a still further object of this invention to provide a construction of pipe such that the same can be readily made of plastic compositions without affecting the smoking quality ;and enjoyment to the user. U Other and further objects .of this invention willbe apparent from this specification, taken in conjunction with the accompanying drawing,

wherein- Figure 1 is an elevational view of a tobacco pipe of my invention;

Fig. 2 is a vertical sectional view .throughthe bowl and a portion of the stem of the pipe of Fig. 1; 1 Fig. 3 is an elevational view of the'tobaccoholding insert of the pipe of Figs. 1 and 2;

Fig. 4 is an elevational view ofthe bowl: and a portion of the stem of a modified construction of tobacco pipe;

Fig. 5 is a vertical sectional view of the modified form of pipe of Fig. 4, and V 7 Fig. 6 comprises a plan and Fig. 7 an elevational view of the modified form of insert as used in the pipe of Figs. 4 and 5.

Referring to Figs. 1, 2 and 3, the pipe comprises a bowl II, a two-part hollow stem l2 suitably joined, and a mouth piece 12. The stem and mouth piece may be of any desired construcion.

The bowl has an enlarged'chambjer [4, below which is a portion l5 of reduced diameter, and a lower chamber l6 withwhich the .tubularstem I2 communicates. These several chambers open intoeach other, and there is a shoulder -Il'be tween the chambers l4 and I5.

A tobacco holding insert [8 is provided. The insert is preferably made of aluminum or other metal of high thermal conductivity, although it may be made of ceramic material, or even "of wood. In the case of aluminum, the insert is provided with a hard, wear-resistant and corrosion-resitant protective coating. Such a coating may be provided by one of the anodic processes, such as by making the insert theanode in'an electrolytic bath containing a sulphuric acid solution; The washing of the aluminum before and after the electrolytic treatment, and the electrolytic treatment'itself cleanses the metal and replaces the soft, natural oxide coating with the hard and resistant protective coating desired.

The insert I8 has straight sides and fiat bottom, the sides being imperforate, but the bottom being providedwitha central aperture-l9. At its upper edge, the insert I8 is provided with a laterially extending flange 2|, which in this instance, is flat and of such a width as to extend across the chamber I4, and overlie the material of the bowl I I. The flange may rest upon the top of the bowl H, or it may be spaced slightly therefrom.

The external diameter of the insert I8 is substantially the same as the diameter of the portion l of the bowl of the pipe so that when the insert is forced into the portion I5 there will be suflicient frictional grip between the same that the insert will be held in place. At the same time, the fit is, for all practical purposes, airtight so that as the smoker draws on the pipe there will be no air leakage around the insert and only the smoke-laden air will be drawn through the opening H3 in the bottom of the insert. The force fit referred to above is only such as can be obtained by the hand of the user, and to remove the insert it is moved from side to side to free the same from the portion l5 whereupon the insert can be lifted from the bowl.

A multiplicity of ventilating apertures 22 are provided through the side wall of the bowl in that part thereof between the shoulder I! and -the:top..of the bowl and on all sides thereof.

I in Fig. 1 has been found satisfactory but these openings can be of any. desired shape and distributed in any suitable manner to accomplish the intended result.

In using the pipe constructed and arranged as described, the smoke-laden air from the tobacco in the insert lSis drawn through the relatively smaller aperture l9 and it at once expands in the chamber l6 Where it has opportunity to further cool before it enters the stem is. The size of the chamber l6 may be varied considerably,

as desired.

While the pipe as just described can be molded of plastic materials, the construction of Figs.

of 4,-5 andfi is better adapted to such manufacture, although this structure is by no means lim ited thereto, and certain features thereof may be used in the pipe of Figs. 1, 2 and 3, and vice versa.

Referring to Figs. 4, 5 and 6, the pipe bowl 3! has a hollow stem EiZ connected thereto. The bowl has an upper enlarged chamber 33 and a lower chamber 34 of smaller area. The inner wall of the bowl is tapered slightly, as indicated at 35, between the chambers 33 and 34.

A tobacco holding insert 35 is provided with imperforate sides 37 and a bottom 38 having a central opening 39. Between the sides and bottom the insert has a tapered portion M of a size and angle to fit the tapered portion 35 of the pipe bowl. The tapered fit provides sufficient friction to hold the insert in place when the same is pressed down and to provide a substantially air-tight seal around the insert, as

and overlies the top of the pipe bowl. In this case the flange is provided with a plurality of corrugations 43 which rest upon the top of the pipe bowl 3| so as to hold the flange above the bowl, leaving spaces 44 therebetween which communicates with the enlarged chamber 33.

In addition, the pipe bowl is provided with a plurality of slots 45 and 46 of different extents respectively which also ventilate the enlarged chamber 33 on all sides of the insert 31. These slots may be of any desired size. The slots 45 extend from the top of the tapered portion 35 to the top of the bowl and the slots 46 are located at the top and bottom of the chamber 33. It will be apparent that the circulation of air in the chamber 33 will be through the slots 45 and 46 and the space 44.

In other respects the pipe of Figs. 4, 5 and 6 operates as described above in connection with the pipe of Figs. 1 to 3 inclusive.

From the foregoing it is apparent that the tobacco pipe of my invention is simple in manufacture, of few parts readily assembled and which may be easily cleaned. Furthermore, the temperature of the smoke is substantially cooler because the temperature of the tobacco chamber is maintained lower than in previous structures, with the added advantage that the fiavor of the tobaccois not affected by high temperatures. Again, thefiavor of the tobacco as it is smoked is not contaminated by any substance of the tobacco holding element and the first and all subsequent uses of the pipe of this invention will be uniformly pleasant.

Modifications may be made in the arrange-- ment and location of parts within the spirit and scope of my invention, and such modifications are intended to be covered by the appended claims. I
